WEB ALIGNING, TENSIONIN G, .AND CUTTING DEVICE.

Application filed September This invention is an improvement on the device disclosed in copending application Serial No. 24,885, filed April 21, 1925 by 'Blanton M. Boyd. In the device disclosed in this copending application the essential feature consists of a series of shutters or slats in cooperation with each of which a roller is provided for limited movement therewith during movement ofthewebs which pass over the rollers, and in which the shutters are also movable with relation to the rollers, butin a diil'erent direction and for a different purpose than the roller movement- Such an arrangement operates 16 very effectively for arelatively small num* ber of webs such as areemployed for certain purposes, but isquite unsuited for devices in which the number of webs which have t be used is relatively large. i

In the present invention the general idea of having shutters and rollersis preserved, but the specific arrangement and operation of these elements relatively to each other is changed in certain respects to comply with the objects of the invention. One of these objects is to produce a web aligning and tensi-oning device which is adapted to ope'r ate "successfully to align and -tension any desired number of webs upon a platen adapted to supportthcm and upon which theyare to be filled in. Another object is to;

- produce a web aligning and; tensioning de vice in which the existing means provided for severing portions of the web 1s so united with the means for operating the aligning and tensioning device that but a single operation is necessary in order to operate both.

These and other objects are attained in the device described in the following specification and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of the device embodying my invention. in the positions its related parts assume when the webs are ready for use.

Fig. 2 is a view similar to Fig. 1, showing the positions assumed bythe .parts during certain periods of the operation of the device.

I In illustrating the embodiment of my invention I have shown a stand which forms a part of a well known style of typewriter equipment. This stand consists of such: main features as legs 6 and 7 which support a table or platen 8 which has side rails .9 and 10 upon which the typewriter moves. At the forward edge of the platen atearing knife 11 is located for movement substantially vertically away from and toward the platen so as to clamp webs upon the platen preparatory to the tearing operation as well as for another purpose which will be ex plained, or to release the. webs so that fresh portions may be provided and the filled in portibns extended beyond the platen for tearing them ofi. The tearing knife is rendered movable by mounting it on arms 12 and 13 which are pivoted at points 14 and 15, see Fig.5, springs .16 and 17 being so connected therewith as to hold the knife normally in clamping engagement with the webs on the platen. A rocker arm 18 which is mounted on a .pivot bar 18, causes the knife 11 to'be operated by extending be neath it and having attached to it a link 19 which is attached to a foot treadle'20 upon a bar 21, so that downward pressure upon the treadle-will lift the knife; The device which has thus far been described is but the usual equipment which is necessary as apartof the, style of typewriter referred J to above, andI will now describe the part which contains the features tained herein.

Rearward extensions of the side rails9 and 10 to an extent to overhang the legs, is provided. This rearwardly extending pair of rails carries between them a frame which of novelty con: 7

consists of side members 22 and 23 which are held apart by a series of slats or shutters ment, as will be-eXpla-ined. Each of the bars 25 is notched at regular intervals to provide a series of upstanding fingers 29 which extend across the slots-27 as'shown in Figs. 1 and 2. These fingers occupy positions back of-the ends 30 of a series of rollers 31' 6X'-' tending between the side members 22 and 23, the ends of the rollers being held yield; ingly against the fingers by springs 32 inside the side members. There are as many rollers as there are slats 24, with the spacing of the rollers such that each roller will be in the same relation to the slat beneath it, with one roller in cooperation with each slat Thus the effect of a pull upon rod 26 will be to draw bars 25'forwardly, thereby moving the rollers from off their cooperating slats and opening a space between each roller and its slat, the former position being shown in Fig. 3 and the latter in Fig. 4. y it may be pointed out that although I have described the slots 27 as being continuous and occupied by the ends of all the rollers, I

may as readily make .individual slots for the occupancy of but one roller end as suggested in Figs. 3 and 4. In such a construction it may be desirable to slant each slot so that each roller, in addition to moving forwardly away from its cooperating slat, will also be lifted somewhat during such movement so as.

to still further clear the slat, as is also subgested in Figs. 3 and 4. And now, in order that the operation of these rollers may be accomplished conveniently and at the proper time in coordination with the operation of the tearing knife 11, I attach a'cable 33 t0 the rod 26 and to the treadle 20 so that simultaneous operation of the rollers and the is that which I have employed to bring about the desired tension upon the springs 32 governing the movement of rollers 26. The lower ends of the springs are attached to a strip 34 which is located in each of and is slidable with relation to the side members 22 and 23. Backward movement of. these strips 34 tinsions the spring and exerts the desired degree of pull upon the rollers, a set screw 35 having been provided to secure each strip in its adjusted position.

I will now describe the operation of the device I have just described, and in doingso will refer frequently to the enlarged frag At this time mental perspective views shown in Figs. 3

and 4:; Inasmuch as this invention is a development of that disclosed in the copending application referred to above, it will be understood that the source of web supply may be from a packet or a roll or rolls located beneath the shutters and rollers, and that each web 36 (see Figs. 3 and 4) is brought up from beneath these elements. The threading of these-webs over the rollers 31 is accomplished by pressing upon the treadle 20, which draws all the rollers forwardly into positions away from the shutters. The rollers are locked in this position by pressing rod 26 downwardly into ends 28 of slots 27. Each web is then passed over its one of the rollers and drawn forwardly so that its apertures'B'? and '38 may be placed upon the books 89 and 40 at the forward edge of the platen 8 The rod 26 is then released and the rollers 31 allowed to return. This allows slight backward movement of each'web and permits the roller over which it passes to pass onto its cooperating shutter, as shown in Fig. 3, thus snubbing or checking the feed of the web from its roll, but operating to until the springs 32 exert the required de--' gree of tension to bring about the desired results. It maybe mentioned at this time that the blade 11 is lifted at the time the rollers are drawing forwardly and that the blade must be raised in order that each of the webs may have their apertures hooked over hooks 39 and 40. Each time each web is stretched upon'the platen it is because of the bringing of the wallso'f its apertures 37 and 38 into engagement with the walls of the hooks. This operation then serves also to obtain accurate registration of any printed forms which may have been provided on the webs, as well as to obtain a web tensioning action. the knife and rollers with the single operating medium 20, simultaneous operation of both is obtained. i v Now. assuming the device ,to have been properly threaded, the platen supported portions of the web are used by filling them in with the desired notations. The treadle 20 is then moved downwardly, thus lifting knife 11 and drawing forwardly all the rollers simultaneously. This enables the forward edges of the webs to be grasped and also frees the webs from the shutters so that there is no drag thereon other than the pull necessary to unwind the webs from their supply roll or rolls. In this manner a larger number of copies may be made simulta neously than would otherwise be possible,

Because of the connection of both because of the easy manipulation, the independent control. of each web and the consedescription as applied to the style of stand I have shown and described.
